Haven’t you ever burst out laughing about something hours or even days later?
You’re always somewhere or doing something that renders said laughter either extremely awkward, inconvenient, or possibly dangerous.
Perhaps you explosively laugh while venom-milking a cobra and fumble either the vial (inconvenient) or the snake (dangerous).
The awkward part is there because your friendĀ thinks you were laughing at her new hairstyle.
Or your the type of person who is a dick and would laugh at your friend’s new hairstyle.
Dick.

Ha, wonderful, it always comes to me when I’m having a serious conversation with my wife…
and she on the other hand does it just like the cartoon…
